About this plant

Hosta 'Krossa Regal' is a large, graceful perennial valued for its bold, blue-gray foliage and architectural presence. Native to Japan, Korea, and China, it features an upright, vase-shaped habit with large, elongated, heart-shaped leaves that add a cool, soothing element to the garden. The leaves are deeply veined with a slightly corrugated texture, enhancing its ornamental appeal. In summer, 'Krossa Regal' produces tall, slender stems topped with racemes of bell-shaped, lavender flowers that rise above the foliage, adding a delicate, airy quality. Thriving in partial to full shade, it is well-suited for woodland gardens, shaded borders, and containers, requiring minimal maintenance and being generally resistant to pests and diseases.

Design tip

Summer flowers carry the middle of the season, so place it where the bed needs color once spring bulbs fade. Keep it out of hot afternoon sun and layer it with woodland companions for a full, settled look.
